Title: Signal transmitter and signal receiver
Inventor: LEONARD ERIC DAVID
IPC: H04L27/00
Filed: 2001-03-01
Abstract: PROBLEM TO BE SOLVED: To use the same hardware component in operation in a TDMA mode and an analog mode. SOLUTION: In transmission in the analog mode, a processor 40 encodes the digital expression of a signal to be transmitted, FM-modulates it to an I-Q pair and outputs it to a digital analog converter(DAC) 31. The DAC 31 converts a digital I-Q pair to an analog signal and outputs it to an I-Q cosign wave generator 32 which generates a common-phase cosine wave and an orthogonal cosine wave having amplitude respectively proportional to the values of I and Q. These consine waves are added for transmission by radio. In the case of receiving in the analog mode, a frequency converter down-converts a received radio frequency(RF) to an intermediate frequency(IF). A digital down converter converts the received signal into digital I value and Q value and outputs them to a processor.
